Abstract

The utility model relates to an airscrew flying disk which is a culture and physical training article for building bodies. The utility model is characterized in that a large round hole is arranged in the midpoint of a plastic disk, a round sheet (1) is arranged in the midpoint of the round hole, the edge (3) of the disk and the round sheet (1) are connected together through airscrew blades (2) which are arranged in the radial direction and are distributed around, and the edge (3) of the disk and the round sheet (1) are fused into integration through hot infusion. The utility model has the advantages of beautiful appearance and complicated and interesting flights. The utility model can strongly train the muscle of a wrist and can train thinking.

Description

Propeller flying dish

With novel a kind of propeller flying saucer, a kind of stationery sports goods that body-building function is arranged of relating to.

Existing flying saucer is a kind of plastics breach of dish shape.Because it is attractive in appearance that profile is owed, the flight path dullness, less demanding to the wrist flexibility ratio during throwing uses its people less at present.

The purpose of art utility model provides a kind of propeller flying saucer, when level is thrown, owing to rotation produces lift, can fly straight up.

The purpose of this utility model is achieved in that and is provided with a circular hole in the center of a plastic disc, be provided with a plastics disk (1) in circular hole central authorities, rim (3) and disk (1) by radially be provided with and along around uniform propeller blade (2) be associated in together, be fused into an integral body by the heat notes, Centromedian disk (1) and radially be provided with order along around uniform propeller blade (2) form a leafy turbine, the propeller blade equal and opposite in direction, shape is identical, all at a slant with 10 °～80 ° angle, when wrist is released flying saucer with certain radian, flying saucer is except that having horizontal velocity, also has a fixed angular speed, so leafy turbine just is subjected to the thrust of certain air, because the resistance of air, angular speed reduces, finally fall, like this, its flight curve becomes second-degree parabola, has also verified this fact by experiment.

The utility model is provided with a leafy turbine in propeller flying saucer center, look and resemble a Xiao Hua, give inspiration, its flight course complexity is interesting, require the radian of wrist swinging bigger during throwing, this has just tempered the muscle of wrist, control flight course, just must think hard, this has just trained thinking.

The utility model accompanying drawing vertical view is 1, and its front view is 2.

According to Fig. 1,2 describe the concrete device details that utility model proposes in detail below.

This device main body is leafy turbine, it be to be positioned at Centromedian disk (1) and radially be provided with and along around uniform propeller blade (2) form, when rotated, can produce lift.

Rim (3) is the outer part of a vinyl disc, and its end is the annular plastics sheet, and it connects mutually with propeller blade, and during throwing, hand grip portion divides for the loss of weight amount, and it requires thin as far as possible.

Propeller blade (2), their shape size is identical, and with 10 °～80 ° angle at a slant, on this angle, in the angular speed of propeller flying saucer, it produces thrust maximum, and it is the base unit that thrust produces.

Whole propeller flying saucer is annotated by heat and is fused into an integral body.

Claims

1, a kind of propeller flying saucer, comprise plastic disc, it is characterized in that: the centre at a kind of vinyl disc is provided with a big hole, circular hole centre be provided with a plastics disk (1), rim (3) and disk (1) by radially be provided with and along around uniform propeller blade (2) be linked together, annotate by heat and be fused into an integral body.

2, flying saucer as claimed in claim 1 is characterized in that: Centromedian disk (1) and radially be provided with and along around uniform propeller blade (2) constitute a leafy turbine.

3, flying saucer as claimed in claim 1 or 2 is characterized in that: equal and opposite in direction, the propeller blade that shape is identical are to be obliquely installed by 10 °～80 ° angle.
